ECE741 Homework #6

1) Does the new clock-tree meet our hold-time safety-margin
   constraint?

(your answer here)

2) Because the new clock-tree has a shorter transition time, it is
   likely to have more buffers.  How many more buffers were needed with
   a clock-uncertainty of 500ps rather than 100ps?

(your answer here)

3) For this design, what is the area penalty of using a clock-
   uncertainty of 500ps instead of 100ps?

(your answer here)

4) For this design, what is the cycle-time penalty (according to the 
   pre-layout Design-Compiler estimates) of using a clock-uncertainty 
   of 500ps instead of 100ps?
